Title: Bi-cmos logic circuit
Inventor: HARA HIROYUKI
IPC: H03K19/00
Filed: 1990-11-28
Abstract: PURPOSE:To increase a level at an output terminal by inverting an output of a signal detection means when the level at the output terminal exceeds the input threshold level of the signal detection means resulting in turning on a 1st MOS transistor(TR) and applying the output of a logic section to the output terminal through the 1st MOS TR. CONSTITUTION:Just after a bipolar TR 16 starts turning on and the charging at an output terminal is started, all the current from an inverter INV is supplied as the base current of the bipolar TR 16 and when the level of an output signal OUT is sufficiently increased, a part of the base current is supplied to the output terminal 17 as a charge current via a MOS TR 19 whose on-resistance is low. Thus, the H level of the output signal OUT is arrived up to a VCC level in a short time. Thus, even when the logic circuit is operated at a high speed, the output signal OUT is arisen up to the power supply voltage VCC.

Abstract: PURPOSE:To prevent a vacuum sealing window from being stuck with a sputtered material by covering the vacuum sealing window of a vacuum vessel by a disk fitted with a slit and allowing r.p.m. of the driving motor of a disk to coincide with the repeated frequency of pulse laser beams via a synchronizing circuit. CONSTITUTION:A disk 19 fitted with a slit is provided to the vacuum side of the vacuum sealing window 18 of a vacuum vessel 11 so as to cover the whole window therewith and this disk 19 is rotated by a driving motor 20. Both the driving motor 20 and a laser 15 are connected to a synchronizing circuit 22 by a wiring 21 and r.p.m. of the driving motor 20 is allowed to coincide with the repeated frequency of laser beams. When laser beams 16 are passed through the vacuum sealing window 8, the disk 19 is regulated so that the slit thereof is just reached the laser beams. Thereby a target 12 can be irradiated with the laser beams 16 but the sputtered material flown to the direction of the vacuum sealing window 18 is cut by the disk 19. Therefore the target 12 can be stably irradiated by the laser beams 16 for a long time.

Title: Method for cracking heavy oil
Inventor: TSUMURA OSAMU
IPC: C10G47/02
Filed: 1991-11-13
Abstract: PURPOSE:To efficiently crack a heavy oil into a light fraction at a high conversion ratio by adding a petroleum fraction having the initial boiling point higher than a reactional temperature and below the boiling point of a heavy oil fraction to the heavy oil fraction and hydrocracking the heavy oil fraction having a specific boiling point with a hydrocracking catalyst at the high reactional temperature. CONSTITUTION:A high-boiling heavy oil such as vacuum distillation residual oil is hydrocracked in the presence of a catalyst according to a suspended bed method, etc., to provide a lighter fraction having high added value such as a fraction, consisting essentially of a vacuum light oil fraction or an intermediate fraction between a vacuum light oil and the stock heavy oil. In the process, a petroleum fraction having the initial boiling point higher than the reactional temperature and <525 deg.C end point is added to a heavy oil fraction having >=525 deg.C boiling point to carry hydrocracking at 350-480 deg.C reactional temperature using a hydrocracking catalyst. Thereby, occurrence of coke on the catalyst and in the reactor, etc., can sufficiently be suppressed and operability can remarkably and stably by maintained even if the operation is performed at a high cracking ratio. As a result, the stock heavy oil can efficiently be converted into a desired light oil fraction at a high conversion ratio and stably converted thereinto.

CONSTITUTION:When the accumulated detergent reaches the prescribed quantity, a second solenoid 26 is operated by a control means 23 and an opening/closing means 25 is moved in a horizontal direction and turned to the opened state. Then, the accumulated detergent falls down on a flowing water surface 10 and flows down together with tap water. After that, the second solenoid 26 is operated by the control means 23 and the opening/closing means 25 is returned to the original state, namely, a state covering an opening part 9. The detergent is accumulated again on the opening/closing means 25. In such a manner, the above mentioned operation is repeated and the rated quantity of the detergent is put-in. After that, the opening/closing means 25 is always in the closed state. Thus, a phenomenon that the detergent is solidified on an abutting surface between a cover 4 and a cover opening plate 20 can be completely prevented.
